IMPROVEMENT IN COMPOUND OXYHYDROGEN BURNERS.

Specification forming part of Letters Patent No. 123,536, dated February6, 1872.

To whom it may concern: v

Beit known that I, Asa W. WILKINSON, of lthe city, county, and State ofNew York, have invented a new and useful Improvement in CompoundOxyhydrogen Bluners; and I do hereby declare the following to bea full,clear,

and exact description thereof, which will enable those skilled in theart to make and use the saine, reference bein g had to the accompanyingdrawing forming part ot' this specication, in which drawing- Figure lrepresents a vertical central section ot' my burner. Fig. 2 is a plan ortop view of the same. Fig. 3 shows a section, and Fig. 4 a plan of myregulating-nipple.

Similar letters indicate corresponding parts.

This vinvention relates to an oxyhydrogen burner which contains a seriesor group of jets, each jet being composed of an external tubecommunicating with a common hydrogenchamber, and of an internaloxygen-tube communicating with a common oxygen-chamber in such a mannerthat the gases admitted to these chambers are conducted to all the jetsand brought in contact at the points ot' combustion, the oxygen beingcarried up through the centers of the hydrogen-tubes, so that the samewill corne in intimate contact with the hydrogen and complete combustionwill be effected.

In the drawing, the letter A designates a burner, the body of which isprovided with two chambers, B G, one of which is situated inside of theother, as shown in Fig. 1 of the drawing; or, if desired, said chambersmay be arranged in any desired relation to each other. The chamber Bcommunicates, by means of a pipe, O, with a generator or reservoircontaining oxygen, and the chamber C communicates, by a'pipe, H, with agenerator or reservoir containing hydrogen, or carbureted hydrogen, orany other combustible gas. From the top D of the two chambers B O rise aseries of jets, eacl of which consists of an external tube, E,Yand aninternal tube, F. The external tubes E oi' all the jets are in directcommunication with the hydrogen-chamber C, while the inner tubes F ofsaid jets communicate with the oxyv gen-chamber B. If the jets andchambers are arranged as shown in the drawing, the communication betweenthe external tube of the central jet and the hydrogen-chamber O iseffected by two channels, a a, provided in the body of the burner, asshown in Fig. l. The

chambers B C are closed at the bottom by a common plate, G, into whichthe pipes O and H are screwed. By removing this plate convenient accesscan be had to said chambers for the purpose of cleaning. The tubes E arescrewed into the top D, so that they canbe readily removed. If the pipesH andv O are opened the combustible gas admitted through the pipe Hpasses through the hydrogen-chamber into the external tubes of theseveral jet-s while the oxygen admitted through the pipe O passesthrough the oxygen-chamber iuto the internal tubes of all the jets, and,as the two gases issue from their tubes, they are intimately mixed atthe point of combustion and a complete bine regulating-nipples I, (seeFigs. 3 and 4,) l

which screw into the top plate D of the chambers B C, and on which thetubes E are screwed. These nipples are perforated with one central holefor the tubes-F, which communicate with the oxygen-chamber, and each ofthe nipples is also perforated with one or more lateral holes, b b,which lead into the hydrogen-chamber. The object of this arrangement isto obtain a uniform supply of hydrogen to all the jets. If the holes b bare all of the same size the jet nearest to the hydrogen supply-pipe Hwill naturally receive more .hydrogen than the jets further' from saidpipe; but by regulating the size or number of the pound jets, E F, theexternal tubes E in `each jet communicating with the chambers C, and

\the internal tubes F with the chamber B, substantially in the manner asand for thel purpose herein shown and described.
